 SERVICE INFORMATION
 GENERAL INSTRUCTIONS
 · Check the ignition system according to the sequence specified in the Troubleshooting.
 · The ignition system adopts CDI unit and the ignition timing cannot be adjusted.
 · If the timing is incorrect, inspect the CDI unit and A.C. generator and replace any faulty parts.
   Inspect the CDI unit with a CDI tester
 · Loose connector and poor wire connection are the main causes of faulty ignition system. Check
   each connector before operation.
 · Use of spark plug with improper heat range is the main cause of poor engine performance.
 · The inspections in this section are focused on maximum voltage. The inspection of ignition coil
   resistance is also described in this chapter.
 · Inspect the ignition switch according to the continuity table specified in page 20-3.
 · Inspect the spark plug referring to chapter 3.
 · Remove the A.C. generator and pulser coil referring to chapter 10.
